Subsidence repairs in Abertillery

Seasonal movement is behind a lot of subsidence, and once its cause is clear it is usually manageable for a home in Abertillery as much as anywhere. The repair that follows is mostly crack stitching, repointing and replastering, with foundation work kept for houses that need it.

What should you know about the ground under Abertillery?

Postcode districts NP13 cover Abertillery, a Gwent town of about 11,000 people. Neighbouring towns we cover: Pontypool (4 miles), Ebbw Vale (5 miles) and Blackwood (5 miles).

Gwent has a mix of ground, with clay in some places and firmer rock in others. Historic coal workings are recorded beneath parts of Gwent, and a coal mining search is worth checking where movement is unexplained. Across Gwent, most homes are valley terraces on steep hillsides, Victorian houses in Newport and Abergavenny, and post-war estates.

What happens during subsidence repairs, step by step?

  1. Send photos or call

    Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.

  2. Deal with the cause

    Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.

  3. Written quote

    We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.

What to look for before calling about subsidence repairs

  • Cracks that open in summer and partly close again in winter
  • Wallpaper rippling or tearing where the wall meets the ceiling
  • Doors and windows that start to stick or no longer close

How we usually approach subsidence repairs

Foundation strengthening

Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.

Best for: Ongoing movement where removing the cause has not worked

Remove the cause, then repair

Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.

Best for: Clay movement or drain leaks where the cause can be removed

Rules for subsidence repairs in Wales

In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.

Questions about subsidence repairs in Abertillery

How much should I budget for subsidence repairs in Abertillery?

Guide prices for subsidence repairs in Abertillery start from about £2,300 per property, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Can you survey a property in Abertillery?

We do. Abertillery and the surrounding area are covered, including nearby Pontypool and Ebbw Vale. A free initial assessment from your photos is the first step.

Why do houses in Gwent crack?

The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.

How do I know if cracks are subsidence?

Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.

Should I cut down the tree near my house?

Not without advice, because felling a mature tree on clay can make things worse. As the roots stop drawing water, the clay swells and can lift the foundations, which is called heave. Pruning or staged removal may be advised instead. Check whether the tree is protected.
